Degraded, highly compacted soils along roadsides present an inhospitable environment for trees and shrubs and lead to the failure of urban landscapes. Developing and testing practices to ameliorate urban soils, thereby improving plant growth and survival, is essential. This research compared the effects of waste-derived soil amendments on woody landscape plants and soil properties on a compacted highway roadside in Tacoma, Washington, U.S., and compared surface application versus incorporation of amendments. Treatments included yard debris compost (surface-applied and incorporated), biosolids blend (surfaceapplied and incorporated), and worm castings (surface-applied only), plus a control with no amendments. Amendments were applied 8 cm deep, and incorporated to a 10–15 cm depth on the tilled plots. An 8-cm layer of bark mulch was blown onto all plots, including the control. Rhus aromatica, Symphoricarpos orbiculatus, and Mahonia aquifolium were transplanted from 3.8 L containers in March 2007. One year later, soil under the mulch/amendments was analyzed for bulk density, total carbon, and nitrogen. Plant growth and survival was evaluated for three years. Incorporating soil amendments reduced bulk density by >50% and increased soil C and N tenfold in the incorporated zone. Soil properties within the surface and control treatments or within the incorporated treatments were not different. All amendments significantly improved plant growth in comparison to the bark mulch control, in the order worm castings ≥ biosolids blend ≥ yard debris compost. Neither plant growth nor plant survival was affected by surface application versus incorporation, and plant roots remained confined to the amended zone.

Cotton Gin

Cotton gin trash, the by-product of the cotton ginning industry which is produced in large quantities every year, can be utilized as feedstock for deriving high quality organic materials such as biochar, compost and co-composted derivates for improvement of soils’ key physical, chemical and biological properties. This is the first report in which cotton gin trash was both thermally and biologically converted at the same time into biochar (BC), compost (C) and co-compost (Coc), and their effects on soil properties and on plant performance were examined. In order to find the optimum rate, the products were used as soil amendments in a greenhouse experiment at 2.5 t ha−1, 5 t ha−1and 10 t ha−1 rates. All of the amendments contributed in improving the soil properties and provided agronomic benefits to plants, however plants (radish var. Cherry belle) showed significantly (p < 0.05) better growth attributes and almost a 315% increase in biomass yield observed when co-composted biochar (10 t ha−1) was applied to the soil, thus suggesting its role in compensating fertilizer application. Amendments (2.5 and 5.0 t ha−1) considerably increased plant growth parameters; however, differences between 5 and 10 t ha−1 amendments were not so significant. As a result, replenishing soil with Coc (5 t ha−1) on a regular basis can promote plant growth and improve soil qualities over time.

Microbiological Indicators

Soil is a non-renewable natural resource, considered as the basis for food production. Changes in soil properties may indicate potentially beneficial or degradative effects of a given management practice, so it is important to select the most sensitive soil properties to act as quality indicators. This research evaluated different approaches to selecting soil quality indicators in the construction of soil quality indices (SQIs). The sensitivity of integrative SQIs, constructed by considering diverse chemical, physical, and biological properties, was compared with biological SQIs, using only biochemical and microbiological indicators, to assess soil quality in an intensive horticultural production system under short- and long-term organic and conventional management. The results provided by the SQIs showed that plots under organic management had increase soil quality compared with the conventionally managed plots, independent of the number of years under production. The SQIs integrated by physical, chemical and biological indicators were more sensitive than indices composed only of biological indicators, as they did not reflect the physical properties of the studied plots. The organic amendments had a great influence on the microbial community; therefore, microbiological indices could not provide reliable information on soil quality in production systems with high inputs of organic materials.

ABSTRACT Green manuring is an important management strategy in tuberous vegetable production systems, since it improves the physical, chemical and biological properties of the soil and, consequently, increases in crop productivity and ecosystem balance. The objective of this work was to evaluate the agro-economic efficiency of carrot cultivation as a function of Calotropis procera biomass amounts incorporated into the soil during two growing seasons in a semiarid environment. The experiments were conducted in an experimental design of randomized complete blocks, with four treatments and five replications. The treatments consisted of four C. procera biomass amounts (20, 35, 50 and 65 t ha-1) incorporated into the soil. In each experiment, one plot with carrot without fertilization (control) was planted, for the purpose of comparison. The characteristics evaluated in the carrot were productivities of total and commercial roots, classified productivity of roots and production economic indicators. The maximum productivity of carrot roots of 35.90 t ha-1 was possible with the incorporation of 47.60 t ha-1 of C. procera biomass into the soil. The maximum net income of R$ 33.744,07 ha-1 in the cultivation of this vegetable it was achieved with the addition of the C. procera biomass amount to the soil of 42.81 t ha-1. The return rates obtained for the carrot cultivation in these optimized quantities were 1.53 and 1.28, respectively, of those achieved in the control treatment (without fertilization).

Abstract The use of organic wastes in agriculture plays a great role in recycling essential plant nutrients, sustaining soil security as well as protecting the environment from unwanted hazards. This review article deals with the effect of different kinds of organic wastes on soil properties and plant growth and yield. Municipal solid waste is mainly used as a source of nitrogen and organic matter, improving soil properties and microbial activity that are closely related to soil fertility. Biowaste and food waste increase pH, nitrogen content, cation exchange capacity, water holding capacity, and microbial biomass in soil. Sewage sludge contains various amounts of organic matter and huge amounts of plant nutrients. Manure is a common waste which improves soil properties by adding nutrients and increases microbial and enzyme activity in soil. It also reduces toxicity of some heavy metals. These organic wastes have a great positive impact on soil physical, chemical, and biological properties as well as stimulate plant growth and thus increase the yield of crops.

Properties Of Soil

After the green revolution excessive use of inorganic fertilizers increased, which resulted in affecting the activities of soil microflora and macrofauna, thus posing an environmental risk and decreasing crop production. The use of organic sources which include biochar, carpet waste, FYM (Farmyard manure) and PGPR (Plant growth promoting rhizobacteria) may act as an important tool to sustainably increase soil organic matter, crop yield and improve soil health on a long-term basis. The results of application of biochar, carpet waste, farm yard manure (FYM) and PGPR showed that the combined application of biochar, carpet waste and PGPR significantly improved soil properties such as organic carbon, nitrogen(N), phosphorus(P), potassium(K), dehydrogenase, alkaline phosphatase activity and microbial population. The enzymatic activity of soil was highly positively correlated with the physicochemical properties of soil. Therefore, it can be concluded that the combination of biochar, carpet waste, FYM and PGPR may increase and sustain the soil properties and crop productivity over time.

Sandy-textured soil infertility poses a problem for sustainable crop cultivation. This problem is usually dealt with by the addition of chemical fertilizers, which are expensive and can cause serious environmental issues if not managed well. A better alternative to improve and manage sandy soil infertility is the use of organic amendments produced from agro-wastes. This two (2)-year field study was conducted in a sandy-textured soil grown with black pepper to evaluate mainly the effects of chemical fertilizer, fermented plant and fruit juices, compost, and biochar on soil properties and morpho-physiological characteristics and yield of black pepper. Generally, the results indicated that the combination of fermented fruit juice, compost, and biochar was comparable to and in some cases better than chemical fertilizer in terms of soil physical, chemical, and biological properties as well as crop performance. These findings were even more pronounced in the second year of measurements. There were strong positive relationships between soil N and pepper leaf chlorophyll content and between soil microbes and soil respiration. The findings showed that these soil amendments produced from agro-wastes are a good alternative to the use of chemical fertilizers on sandy soils to improve soil fertility and productivity and the yield of black pepper sustainably.
